### Running the python script run_alphafold.py directly
103 103
run_alphafold.sh is a convenience wrapper script that shortens the required command arguments to run_alphafold.py. The run_alphafold.py script is also available which requires all parameters to be set explicitly, but provides greater flexibility. Pass --helpshort or --helpfull to see help on flags.

Memory is going to be an issue with larger protein sizes. The original publication suggests some things to try:
107 107
108 108
"Inferencing large proteins can easily exceed the memory of a single GPU. For a V100 with 16 GB of memory, we can predict the structure of proteins up to ~1,300 residues without ensembling and the 256- and 384-residue inference times are using a single GPU’s memory. "
109 109
110 110
"The memory usage is approximately quadratic in the number of residues, so a 2,500 residue protein involves using unified memory so that we can greatly exceed the memory of a single V100. In our cloud setup, a single V100 is used for computation on a 2,500 residue protein but we requested four GPUs to have sufficient memory."

The pTM scores are not calculated using the default model. To get pTM scored models you need to change the model names in the input. We have provided a template wrapper script (https://sbgrid.org//wiki/examples/alphafold2) which you can change to your requirements. To get pTM scores you will need to change the model_name line to "model_1_ptm,model_2_ptm" etc.
